Yeah, it seems like an odd list, and no doubt it could have been better. But: in a survey you can only ask a handful of questions.

(BTW: I assume CR actually did the survey, or at least referred to a decent one; they're a pretty credible outfit, in my experience; they're definitely on my go-to list when I'm car shopping.)

So standing back from it: are some/all of these questions credible as "diagnostic points" -- the tip of the iceberg that gives an indication of what's below the surface? Does it suggest people are starting to think about this subject even a little?
